About Project

The project is like a backend-service of a message program. It serves an endpoint to accept messages then it produces a rabbitmq message. Another service that consumes rabbitmq catches that message and write the message to the redis in a format that each sender-receiver grouped messages are sorted in chronological descending order. The last service is the reporting service which serves an endpoint to list all messages in chonological descending order with corresponding sender-receiver pair.

Local Setup

Firstly, you need to up the redis and rabbitmq containers which are configured in docker-compose.yml

   docker compose up -d

Then Execute:

    go run main.go

Endpoints

GET: /message: When you hit that endpoint with the request has body like {sender:"", receiver:"", message:""}, it takes that message and publishes that message to the rabbitmq.

GET: /message/list?sender=x&receiver=y When you hit that endpoint with query params sender:string, received: string,It reads the redis for senders message sent to receiver and returns a list of object array in a format like [{sender:"", receiver:"", message:""}, {sender:"", receiver:"", message:""} ] and in a chronological descending order.
